Monkey Life was created in 2006 and has continuously documented the work of Dr. Alison Cronin, MBE and her team at Monkey World; Ape Rescue Centre.

Filmed at Monkey World in Dorset, Monkey Life follows the rescue and rehabilitation of abused and neglected primates. Many have mental as well as physical problems so the Primate Care Staff treat their individual needs until they can be reintegrated with primates of their own kind. The primates at the park range from apes, who were taken from the wild as babies and used as photographers props on Spanish beaches to monkeys, many of which were rescued from the UK pet trade.

With unparalleled access Monkey World's dedicated team are filmed dealing with medical emergencies, primate moves, births and sometimes heart-breaking decisions. We follow Dr. Alison Cronin, MBE around the globe as she continues the park's mission to rescue abused primates.
